Theoretical Probability Quotes & Sayings

The incomplete knowledge of a system must be an essential part of every formulation in quantum theory. Quantum theoretical laws must be of a statistical kind. To give an example: we know that the radium atom emits alpha-radiation. Quantum theory can give us an indication of the probability that the alpha-particle will leave the nucleus in unit time, but it cannot predict at what precise point in time the emission will occur, for this is uncertain in principle. — Werner Heisenberg

There was nothing abstract or theoretical in his world. The stars had no significance. The sky was not interesting unless it showed probability of rain. He ate corn, corn, corn. He ate beans, beans, beans. — Warren Eyster
